Application filed October 21, v1918. Serial No. 258,982.

To all who/a t may concern.'

Be 1t known that' I, JoHN H. COMER, a

citizen of the United States, residing at Lib-v erty Hill, in the county 01"" lVilliamson and State ot Texas, have invented new and useful Improvements in Silos, of which the following is a specification. y

Thisinvention relates to a silo, and more particularly to a device of the type indicated intended to be constructed in sections,

to permit of shipment in a knock-down con- 'plurality of segments constructed as indicated and eachprovided With a portion at the edge thereof designed to overlap an adjacent segment, with means for temporarilysecuring' the segments during construction, andcertainlnovel means for permanently securing seA ents.- l n A stillY urther'object is to provide a structure formed as indicated and including annular members built up of segments formed of overlapping istrips of material, these segments being secured together by te sion means and serving to retain the longittl ilial segments of the structures permanently in position to form the complete device.

. With the foregoing and other objects nl View, the invention consists in the 'novel construction, combination, and arrangement of elements hereinafter described and claimed.

In the drawings,

Fig. 6 is a transverse section on the line 6-6 of Fig. land showing means for securing the door.

In carrying'out my invention I provide a structnre comprisinga plurality of longitudinal segments, which Will be termed sections in order to distinguish them from the portions or parts of the rings or hoops surrounding the structure and retaining the longitudinal sections in position.

The longitudinal sections referred to are designated at 10 and each comprises an inner layer of' longitudinal strips .11, and an outer layer of longitudinal strips 12, these layers being separated by a sheet of insulating material, designated at 13. This insulating material may be of any suitable com#vl mercial type of rooting material. At one edge portion of each section 10 the outer layer overlaps the inner layer, and at the opposite edge ofeach section the inner layer overlaps the -outer layer, thus vproviding' for the overlapping of adjacent segments orsections throughout the circumferential porl tion of the structure as completed.

In order to temporarily retain the longitudinal sections of the structures in position, during erectiom-I provide segmental hoop portions designated at 16, each segment having secured to the outer edge thereof a metallic band 17. Ears 18 project laterally from the end of each segment, and

the ears are provided with apertures 20,l

bolts passing through adjacent ears of adjacent segments, and serving to secure the several segments of a complete ring or hoop in pcsition for temporarily retaining the lengitmlinal seht/ions of the structure, until permanent seclh'ln means are provided.

.After the wofll' es been completed o the point indicated, the permanent cirdu ferential bands or hoops are applied, be ri ming at the `bottom of the structure. T e first temporary annular member or hoop is removed, and a permanent` circumferential band 25 is placed in position and suitably secured. This band is built up from :t plurality of segmental portions. Aninnerband the joint. Finally an additional narrowr band is applied over the band 26, the various portions being secured by nailing, or in any other suitable manner.

After the permanent circumferential bands have been applied in the manner indicated, a tension device comprising a metallic band 30 is passed around the built up bands, the ends of the tension band being threaded into engaging devices 31 and 32. All of the `temporary circumferential members are replaced in a similar manner, and the main portion of the structure is complete. A top is shown at 35 and a ladder extends from the bottom to the top, the ladder being designated at 3G.

Certain of the longitudinal sections of the complete structure are provided with doorways at points on opposite sides Aof the ladders, and arranged in the relative positions shown. The doors are designated l0 and are each formed ot inner and outer layers of longitudinal strips, the inner layers being designated l2 and the outer layer These layers are separated by stripsl of insulating material, 44, as is the case of the longitudinal sections ot the completed structure. rllhe doors open from the inside, and the inner layer or portion 42 overlaps the edges of the outer layers on all sides, and all of the edge portions of the inner`a'nd outer layers are covered vvith insulating material. The edge portions or' the door-Way are correspondingly formed, so that the outer layers of longitudinal strips along the lines of the edge of the door-Way overlap ithe edge of the inner layers of longitudinal strips, this arrangement providing an effective joint practically air tight. Transverse metallic strips t8 aid in retaining the strips of the outer portions of each door in position, and pivoted fastening devices 15 serve to secure the doors and prevent displacement from any accidental cause.

It is obvious that the relative sizes and proportions oi the various elements may be varied as may be desired, and other minor changes may be made Within the scope of the appended claim.

Having thus described my invention I claimz- In a device of the class described, a plurality of' longitudinally extending sections forming segments of a cylindrical structure, the edges oi the sections overlapping, circumferential members surrounding the sections at intervals and formedfof .assembled strips forming continuous layers circumferentially, certain of the layers being narrower than others, and adjacent layers overlapping along circumferential lines to form broken joints, and tension devices surrounding the circumferential members and comprising hoops of approximately the width of the yassembled strips, and means for se curing the ends of the tension members.

In testimony whereof l affix my signature.

JOHN H. COMER.
